Mechanical Properties of MWCNT Reinforced Aluminium Nano Composites Synthesized Through Powder Metallurgy
Abstract: Multi-wall carbon nanotubes (MWCNTs) reinforced aluminium nano composites were synthesized using powder metallurgy technique and then cold extruded as secondary process. CNTs were added by 0.5wt%, 1wt%, 1.5wt% with aluminium powders and ball milled to obtain homogeneous mixture. The effects of carbon nano tubes (CNTs) on the mechanical properties of Al were investigated. The effect of mixing through ball milling, sintering temperature and extrusion process on the microstructure is explored. …

Nanostructured TiO2 Prepared Through Sol–Gel Method Enhances the Activity of Antibiotics against Gram Positive Bacteria
Abstract: The synthesis and bioactivity of titanium dioxide (TiO2) nanoparticles has been extensively studied. However, the antibacterial activity of TiO2 individually or in combination with different antibiotics has not been demonstrated. TiO2 was prepared by sol–gel process using precursor Titanium (IV) Chloride (TiCl4) and concentrated sulfuric acid in 4 h of calcinations at 550 °C and the enhancement effect of TiO2 nanoparticle on the antibacterial activity of different antibiotics was evaluated …

Prediction of Scale Dependent Material Properties of Single Walled Carbon Nanotubes
Abstract: The present work explores the potential application of nonlocal continuum mechanics related to nanotechnology applications. Nonlocal continuum models represent attempts to extend the continuum approach to smaller length scales while retaining most of its many advantages. This paper presents the prediction of nonlocal scaling parameter for single walled carbon nanotubes. The scale effects are introduced into the continuum models using non-local elasticity constitute model. A relationship among the carbon nanotube …

Synthesis of Metallic Copper Nanoflowers, Nanocrystals and Nanorods using Electrodeposition and Hydrothermal Techniques
Abstract: Copper nanoflowers and nanocrystals have been fabricated using two different techniques; electro-deposition of copper in polymer and anodic alumina templates (AAT) and Cetyltrimethyl-ammonium Bromide (CTAB)-assisted hydrothermal method. Nanorods of copper are produced by electrodeposition in 100 nm AAT. Scanning Electron Microscope (SEM) micrographs record some interesting morphologies of metallic copper nanoflowers and nanocrystals. Field Emission Scanning Electron Microscope (FESEM) has been used to determine morphology and chemical composition of polycrystalline …
